Crown Self-Contained Hydraulic Valve Actuation System

Protecting Your Personnel, Facilities, Environment, and Natural Resources

Stream-Flo’s Crown self-contained hydraulic valve actuation system is used for the automatic operation of actuated ball valves and gate valves on wellheads and flow lines under emergency conditions. The system consists Crown Hydraulic Actuator and Reverse-Acting Gate Valve.

Key Features:

Self-Contained System: Operates independently, releasing no emissions and using clean, contaminant-free, closed-loop hydraulics. Eliminates reliance on external power sources such as electricity or flow line pressure.

Eco-Friendly Operation: The system’s hydraulic fluid is recycled and reused, ensuring zero environmental discharge, thus protecting both operators and the environment.

Ideal for Remote Applications: Designed for locations lacking reliable power or where power solutions are cost-prohibitive.

Modular Design: The actuator is independently assembled and tested, facilitating easy replacement and minimizing downtime.

High Safety Standards: Equipped with safeguards like metal-to-metal back seat, self-energized stem packing, and a vented bonnet assembly to prevent fluid entry into the actuator.

Corrosion Resistance: Features a sealed spring canister and internal components that prevent corrosion, reducing maintenance needs and operational downtime.

Advantages:

Minimal Maintenance: The self-energized stem packing ensures long-term, maintenance-free sealing.

Flexible Installation: The bolt-on reservoir allows for local or remote mounting, promoting adaptability in diverse field conditions.

Operator Safety: Includes a relief valve to keep the spring canister non-pressurized and prevent accidents.

Robust Design: The spring is encapsulated with high preload for secure shut-in, ensuring personnel safety.

Integrated Controls: The Pump Control Unit can be triggered by multiple sensors and can be integrated with SCADA systems for streamlined operations.

Applications:

Surface Safety Valves (SSV)
Emergency Shut-Down (ESD) Valves
High-Pressure, High-Temperature Wells
Injection Wells (CO2, Steam, Water Disposal)
Blow-down and Flow Lines
High Integrity Protection Systems (HIPS)

Specifications:

Actuator Pressure: Maximum operating pressure of 3500 psi.

Temperature Range: Operates between -50°F (-46°C) and +180°F (+82°C).

Valve Sizes: Available from 1-13/16” to 11” with API working pressures up to 20,000 psi.

Enhanced Safety Measures:

Fire-Safe and SIL 3 Capable: Designed to meet strict performance requirements and specifications, ensuring fail-safe operation even under critical conditions.

Closed Hydraulic Circuit: Moves hydraulic fluid between components without environmental exposure, upholding environmental safety protocols.
